The answer is ultrafiltration. This is helped by the hydrostatic pressure and blood pressure in afferent renal arteriole. Molecules such as water, glucose, urea, sodium chloride, amino acids pass through the semipermeable membrane of the dense capillary network of the glomerulus to form glomerular filtrate. Some of these molecules are later reabsorbed in the renal tubules.
Exocrine pancreatic insufficiency (EPI) causes problems in how you digest food. Your pancreas doesn't make enough of the enzymes that your body needs to break down and absorb nutrients. Enzymes speed up chemical reactions in your body. The enzymes made by your pancreas move into your small intestine, where they help break down the food you eat. When you have EPI, you don't get the nutrition you need because your body can't absorb fats and some vitamins and minerals from foods. You might lose weight or have pain in your belly.
Answer:
A) nutrient A only
Explanation:
In this case, enzyme A is required for the digestion of nutrient A, thereby evidencing that the mutation affects the enzymatic pathway and the mutant strain only can grow by supplementation with this nutrient. In molecular biology, mutant strains are useful to study enzymatic functions (for instance, the role of enzyme A in nutrient assimilation), as well as to examine downstream signaling pathways.
In experimental design, spontaneous mutations are induced to study their effects on the phenotype. Subsequently, reverse mutations may also be induced to reverse the forward mutation, thus restoring the original wild-type phenotype.
Answer:
C. the causes of cancer are not usually genetic.
Explanation:
The genetic code is being carried by the DNA molecules which are found in most organisms.
DNA it is called Deoxyribonucleic acid. It is a thread-like known as nucleotides which carry genetic instructions which are used for growth, functioning, development, and reproduction.
Both RNA and DNA are nucleic acids. DNA stores biological information. DNA is the backbone in resistance cleavage and is made from alternating sugar and phosphate.
